Objective: Simulation based training with training models is being increasingly used as a tool to help trainees mount the learning curve. However, validation studies of surgical simulators are often limited by small numbers. We aim to evaluate the feasibility of validating simulation-training tasks in laparoscopy and flexible ureteroscopy (FURS) rapidly at a large-scale conference setting for residents. Methods: Seventy-six urology residents from various Asian countries were assessed on their laparoscopic and FURS skills during the 14th Urological Association of Asia Congress 2016. Residents performed the peg transfer task from the fundamentals of laparoscopic surgery (FLS) and completed inspection of calyces and stone retrieval using a flexible ureteroscope in an endourological model. Each participant's experience (no experience, 1–30 or >30 procedures) in laparoscopy, rigid ureteroscopy (RURS) and FURS was self-reported. Results: Median time taken to complete the laparoscopic task decreased with increasing laparoscopic experience (209 s vs. 177 s vs. 145 s, p=0.008) whereas median time taken to complete the FURS tasks reduced with increasing FURS experience (405 s vs. 250 s vs. 163 s, p=0.003) but not with RURS experience (400.5 s vs. 397 s vs. 331 s, p=0.143), demonstrating construct validity. Positive educational impact of both tasks was high, with mean ratings of 4.16/5 and 4.10/5 respectively, demonstrating face validity. Conclusion: Our study demonstrates construct and face validities of laparoscopy and FURS simulation tasks among residents at a conference setting. Validation studies at a conference setting can be an effective avenue for evaluating simulation models and curriculum in the future.
